Abstract:
A method for determining an accident risk of a first object with at least one second object is proposed, a collision probability and a hazard probability of the at least one second object being determined in a predefined region around the first object, the collision probability and the hazard probability being determined as a function of motions and object classes of the first and the at least one second object. The accident risk is then determined as a function of the collision probability and the hazard probability.
Abstract:
A bearing system for a water lance of a water lance blower contains a ball joint having a ball with a surface and a diameter. The ball further has a passage, on and/or in which the water lance can be disposed. The bearing system is characterized in that a ball seat is provided and contains two axially interspaced bearing shells each of which has an opening, whereby the ball protrudes at least partially into the openings. A method for operating the bearing system that seals gaps, which can occur as the ball rotates, between the surface of the ball and the spherical contact surface of the at least one bearing shell. The bearing shells enable the bearing system to be easily assembled, and the small contact surfaces reduce the amount of friction during operation. In addition, the bearing system is also suited for use as a seal.
Abstract:
A water lance blower for cleaning heat installations is disclosed. A water lance linked with a water feed conduit system is swivel-mounted with its orifice disposed in a hatch. The water lance can blow a jet of water through the heating installation in operation and through which flames and/or flue gases are guided to wall areas that can be reached from the hatch. The water lance blower is provided with a drive system with at least two drive units that control the water lance, and with a holding device that fastens the water lance blower onto the heating installation. Further, parts of the water feed conduit system are integrated onto the holding device, thereby substantially limiting the size of the water lance blower to the swivel range of the water lance.
Abstract:
A water lance blower for cleaning heating installations, wherein a water lance (6) is movably (5) arranged with its mouth on or in a hatch (2) and can blow a water jet through the heating installation, which is in operation and is flowed through with flames and/or smoke, onto wall areas (A-E) which can be reached from the hatch (2), wherein the water lance (6) is movable by at least one movement element (8.1, 8.2, 8.3) which is stationarily fixed at one end outside a vertical plane through the point of movement (5) of the water lance (6) to the heating installation and by the other end (7.1, 7.2, 7.3) to the water lance (6), wherein path sensors are provided for precise determination of the position of the water lance (6). Preferably three movement elements (8.1, 8.2, 8.3) are provided, the fixing points (9.1, 9.2, 9.3) of which each form in particular an angle of approximately 80.degree. to 140.degree. to the point of movement (5) of the water lance (6). Such water lance blowers can be installed even when there are unfavorable spatial conditions and perform any freely pre-determinable blowing patterns and speed profiles.
Abstract:
A method for determining an ego-motion of a vehicle is described, which is carried out in driver assistance systems, particularly in parking assistance systems. The method involves: taking a sequence of images, successive in time of a vehicle surroundings by a vehicle camera; determining, based on the image sequence, at least one motion flow with regard to an object in the vehicle surroundings; and determining the ego-motion of the vehicle based on the at least one motion flow.
Abstract:
A circular saw including a saw blade (36) which may be rotatingly driven about a rotational axis, and at least one first splitting wedge is described. The circular saw is configured so that the first splitting wedge is movable relative to the rotational axis of the saw blade.
Abstract:
A method for assisting a driver in lane guidance of a vehicle on a roadway includes: displaying a recorded image to the driver on a display unit, which image represents the vehicle surroundings; reading in an operating signal input on a user interface by the driver; selecting an object contained in the image, using the operating signal; displaying a mark on the display unit, the mark being displayed in an area of the image which represents the object; using the object for determining at least one longitudinal control parameter for a driving route to be traveled by the vehicle in order to assist the driver in lane guidance.
Abstract:
A device for classifying at least one object in the surrounding field of a vehicle with the aid of an environmental sensor system, the device classifying the at least one object on the basis of its shape and its dimensions, and the environmental sensor system ascertaining the dimensions.

Abstract:
An apparatus (1) for the cleaning of a boiler (2) by means of a cleaning fluid (3), with at least one cleaning appliance (4) which comprises means for aligning a fluid distribution device (5) with inner regions of the boiler (2), the at least one cleaning appliance (4) being surrounded by a container (6) and being mountable onto a connecting nipple (8) of the boiler (2) by means of at least one connection piece (7). Particularly preferred application possibilities and operating methods are also explained.
